- 9. The image forming apparatus according to claim 5, wherein the front cover defines a third opening, and manually fed recording medium is transported from the third opening to the process unit.
- 10. The image forming apparatus according to claim 9, wherein recording medium fed from the feed cassette and recording medium fed from the third opening are transported along a common paper feed path by the transport unit to the process unit.
- 11. The image forming apparatus according to claim 9, wherein the third opening is a slit formed integrally with the front cover.
- 12. The image forming apparatus according to claim 11, wherein the front cover is pivotable about a bottom end of the front cover, the slit being formed above the bottom end.
- 13. The image forming apparatus according to claim 11, further comprising:a fixing unit that fixes the image formed on the recording medium; wherein the transport unit forms a substantial straight path from the slit at the front cover to the fixing unit.
- 14. The image forming apparatus according to claim 11, further comprising:a resist unit provided at a common paper path between the feed cassette and the process unit; wherein the recording medium from both the feed cassette and the slit is transported via the resist unit.
- 15. The image forming apparatus according to claim 11, wherein the recording medium from the slit are transported to the process unit along a common paper path by the transport unit.
- 16. The image forming apparatus according to claim 1, wherein the process unit has at least a photosensitive drum, and the process unit is detachably attachable to the housing in a direction perpendicular to an axial direction of the photosensitive drum.
- 17. The image forming apparatus according to claim 1, further comprising:a guide that guides the recording medium from the feed cassette to a common paper feed path so that feeding direction of the recording medium is reversed.
- 18. The image forming apparatus according to claim 1, wherein a planar portion is formed on an upper surface of the housing.
- 19. The image forming apparatus according to claim 18, further comprising a laser scanner unit disposed at an upper portion of the process unit mounted within the housing.
- 20. The image forming apparatus according to claim 18, further comprising a cover disposed on the planar portion, the cover defining a cutaway at a front side of the housing, the cover and the discharge unit defining a space to accommodate discharged recording medium that is stacked, wherein the discharged recording medium is removable through the cutaway.
- 21. The image forming apparatus according to claim 18, further comprising a peripheral device disposed on the planar portion, the peripheral device being operable from the front side of the housing.
- 22. The image forming apparatus according to claim 21, wherein the peripheral device disposed at the planar portion is an image scanner.
- 23. The image forming apparatus according to claim 21, wherein the peripheral device disposed at the planar portion is a facsimile reception/transmission machine.
- 24. The image forming apparatus according to claim 18, further comprising a stepped portion provided between the discharge unit and the planar portion, the stepped portion defining a space to accommodate discharged recording medium that is stacked.
- 25. The image forming apparatus according to claim 24, wherein the stepped portion has a height of at least 1 cm.
- 26. The image forming apparatus according to claim 1, further comprising a laser scanner unit disposed at an upper portion of the process unit mounted within the housing.
- 27. The image forming apparatus according to claim 1, further comprising a peripheral device disposed at an upper portion of the process unit and mounted within the housing.
- 28. The image forming apparatus according to claim 27, wherein the peripheral device is a reading/communication unit.
- 29. The image forming apparatus according to claim 28, wherein the reading/communication unit has an image reading function and an image transmission/reception (facsimile) function.
- 30. The image forming apparatus according to claim 29,wherein the reading/communication unit further comprises: a document tray; a document discharge tray; and a second operation panel, wherein the document tray, the document discharge tray and the second operation panel are operable from the front side of the image forming apparatus.
- 31. The image forming apparatus according to claim 30, wherein the reading/communication unit includes an image reader that reads at least one document received from the document tray.
- 32. The image forming apparatus according to claim 30, wherein the document discharge tray is located above the discharge unit.
- 33. The image forming apparatus according to claim 29, wherein the reading/communication unit further comprises a telephone unit having a telephone function.
